1. 以ing结尾的形容词。2. 以ful结尾的形容词。3. 以ed结尾的形容词。4. 多音节的形容词。（三个或三个以上音节构成的单词， 我们把他们称为多音节， 如：ppular 就是多音节单词
比较级，要变化一般词尾加er。(lng-lnger, tall-taller)词尾若有哑音e, 直接加r就可以。(nice-nicer)重读闭音节,单辅音字母要双写。(ht-htter, big-bigger, thin-thinner)辅音字母若加y, 记得把y变为i。(happy-happier, funny-funnier) 多音节更容易，词前加mre 便可以。(utging- mre utging)
（1）比较级与最高级的结构可以转换，意思不变。如：The Changjiang River is the lngest river in China. 长江是中国最长的河流。= The Changjiang River is lnger than rivers in China. = The Changjiang River is lnger than river in China. （2）当某一事物与其他事物作比较时，被比较事物中不能包括本身。如： He is taller than student in his class. 他比班上其他学生都高。（3）如果比较对象相同，可用that / thse代替第二个比较对象。如： The fd in Sichuan is htter than in Guangdng. 四川的食物比广东的食物辣。
（4）“the+比较级，the +比较级”表示“越...，越...”。如：The , the . 越多越好The yu are, the mistakes yu’ll make. 你越仔细，错误就越少。（5） 表示两者中“较……”时，用“the + 形容词比较级+ f短语”来表达。 如：Canada is the tw cuntries. 加拿大是这两个国家中较大的那一个。（6）形容词的比较级可用much, a little, a lt, even等修饰，使原本的比较级在语意上更加明确。如：Apples are than ranges. 苹果比橘子大得多。Let’s g t schl . 我们早一点去学校吧。
mre careful

最高级，很容易，一般词尾加est。 (cheap— cheapest) 词尾若有哑音e, 直接就加st。 (clse— clsest) 重读闭音节， 单辅音字母要双写。 (big— biggest) 辅音字母若加y, 记得把y变为i。 (friendly— friendliest) 多音节，考考你， mst到底加哪里？ (ppular— mst ppular)
形容词副词比较级最高级的构成（3）——不规则变化：构成口诀
最高级表示“最……”，表示三者或三者以上(人或物)进行比较，其中有一个在某一方面超过其他几个时用。 1.形容词最高级前一般要加the，但如果其前有形容词性物主代词或名词所有格等修饰语时, 则不再用定冠词the。副词的最高级前面可以加定冠词the, 也可以省略。 e.g. This bk is the mst interesting ne. Her yungest daughter is eleven years ld. Liu Jun ran (the) fastest in the race.
2.形容词的最高级常用“the + 最高级+ 比较范围”结构, 比较范围为短语（介词in或f短语）或从句。 一般情况下, 如果主语与介词短语中的名词属于同一类, 用介词f; 如果不是同一类, 则用介词in。 e.g. Tina is the mst utging in her family. Jim jumps (the) highest f all the bys. The dg is the best present that I have ever received.这只狗是我收到过的最好的礼物。
